Have the book in front of you and want to add it to your Zotero library without having to search for a citation?
Use the "Add Item by Identifier" feature.
If you have a book's ISBN, an online article's DOI or PMID number, just click the magic wand button: "Add item by identifier." Type in the book or article's number, and Zotero will automatically download its information and save it to your library.
To archive a web page, click the “Create New Item from Current Page” icon (). This will create a web page item in your library with basic information from the page.
If “Automatically take snapshots when creating items from web pages” is enabled in the General pane of the Zotero preferences, a copy of the web page will be added as a child item. To see the page as it was on the day you captured it, double-click the snapshot icon, as shown below.

Tagging is an easy way to categorize items by attaching descriptive words to them. You can tag your information with whatever relevant keyword or term you would like associated with that given item. These tags allow you to sift through your information in a personal way, by the categories that you deem relevant.
When you import items via library databases or catalogs, be aware that tags are sometimes automatically imported alongside these items, using information stored in the database. You may want to keep or delete these tags, depending on their relevance and utility.
To add a tag to an item simply select the tags tab in the right column and hit the button.

Zotero can make files available to users in two ways: by storing a copy or by linking to them. Storing a copy will add that file to the Zotero data directory, separate from the original file. Linking will simply refer to the original file without creating a copy or changing its location. Stored files will be included with any file sync, while linked files will remain only links. Any type of file can be added to the Zotero library, either on its own or associated with another item.
